Install your modular switches with confidence using the MK K8891ALM Surface Metal Box. Part of the heavy-duty Metalclad Plus family, this box provides a secure and impact-resistant housing for 1-module and 2-module Grid Plus arrangements, ensuring your electrical points are protected in demanding locations.
Built for Durability & Ease of Install:
-
1 & 2 Gang Versatility: This universal square box accommodates both the 1-gang (K3701) and 2-gang (K3702) Grid Plus mounting frames.
-
Tough Metalclad Construction: Manufactured from heavy-gauge steel with a corrosion-resistant metallic powder paint finish. The smooth, rounded corners reduce the risk of injury and provide a professional, clean look.
-
Self-Levelling Platform: A unique internal design feature that ensures the mounting frame is always positioned correctly without the need for manual adjustment, saving time during final installation.

Multiple Knockouts: Equipped with 5 or 6 x 20mm knockouts (depending on batch/entry points), plus a base knockout, allowing for flexible cable entry from any direction using standard conduit or glands.
Industrial Applications:
-
Perfect for Rough Environments: Specifically designed for areas where impact resistance is a priority, such as tool sheds, factories, and commercial warehouses.
-
Logic Plus & Metalclad Compatible: While designed to house Grid Plus modules, it is perfectly color-matched to the Metalclad Plus range of frontplates for a unified industrial aesthetic.
